Abstract: A method of manufacturing a surface fastener includes a molding step of molding at least a base part by feeding molten synthetic resin from a feeding nozzle part to a die wheel that is rotating in one direction. The molding step includes molding the base part in a state where at least one of the feeding nozzle part and the die wheel has a temperature difference between at least two positions that are different in a cross direction, the temperature difference being produced by heating with a heater part. The method enables the manufacture of a surface fastener including a base part whose thickness is uniform or substantially uniform in the width direction and being less likely to have wavy wrinkles even after being wound onto a collecting roller.
